MCQ: The number of equilibrations required using fresh organic phase each time and equal volumes of each phase to achieve a 99.5% extraction of substance with a partition coefficient of 3 is -3 -2 -4 -5 -5
Added by Molly M.
Step 1
The partition coefficient (K) is given as 3, which means the ratio of the concentration of the substance in the organic phase to the concentration in the aqueous phase is 3:1. Since we are using equal volumes of each phase, the fraction extracted in each Show more…

A substance with a partition coefficient of 4.7 is extracted into an organic phase by successively using 5 equal volumes. If the initial aqueous solution was 111 mL, how much organic solvent (total) would be needed to extract 95% of the substance? Report your answer in mL

Solute A has a partition coefficient of 3 between toluene and water, with three times as much in the toluene phase. Suppose that 100 mL of a 0.010M aqueous solution of A is extracted with toluene. What fraction of A remains in the aqueous phase, if five extraction with 100 mL is performed?
Calculate the partition coefficient for the analyte when an unretained solute passes through a chromatography column in 3.7 min and the analyte requires 8.4 min. Assume the volume of the mobile phase is 1.4 times the volume of the stationary phase.
